Simplest way is to check if there are any dots ('.') in that string

10.100.13.42 == IPv4
::ffff:10.100.13.42 == IPv4 10.100.13.42 in IPv6 way
3ffe:7357::1 == IPv6 "native"

Oh btw... above behaviour depends on the version of Apache and the
stack...
So sometimes the middle version doesn't pop up... but the dot-check
stays valid...
And don't complain if you got resolving turned on ofcourse...
